A "Choose-Your-Own" Classroom-Based Activity That Promotes Scientific Inquiry About Rna Interference, Jeremy L. Hsu

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

RNA interference (RNAi), the process that results in the degradation of a target gene’s mRNA, is a fundamental part of eukaryotic gene regulation and is also an important molecular technique that allows for experimental manipulation of gene expression without altering DNA sequences. Despite the importance of RNAi, there have been relatively few lecture-based activities designed to teach about the consequences of this process and counter common misconceptions. I present here an inquiry-based activity that is centered around a “choose your own experiment” design where students generate hypotheses and critically evaluate their ideas by choosing several simulated experiments. The activity presents …

A Mixed-Methods Study Of Entomology Incorporation In U.S. Secondary Science Instruction, Erin M. Ingram

Department of Entomology: Dissertations, Theses, and Student Research

To encourage understanding and appreciation of insects, entomology education advocates have supported and encouraged K-12 teachers to integrate insects and insect-related content into formal science instruction. However, research examining how and why science teachers incorporate entomology into secondary science courses is limited.

A sequential explanatory mixed-methods research study was conducted to address this gap. The study was conducted in two phases. During the first phase, quantitative survey research was conducted with a representative sample of 254 U.S. secondary life science teachers. During the subsequent qualitative phase, follow-up interviews were conducted with a purposeful sample of 18 survey participants and an …

Promoting Stem Teacher Reflection Through Self-Evaluation, Steven W. Mumford, Kathryn Newcomer

Political Science Faculty Publications

Evaluators face serious challenges assessing the impact of teaching practice on student outcomes, such as for assessing the impact of grant-funded teacher training programs. To overcome these barriers, the evaluators of an NSF-funded teacher scholarship program elected to coach teachers on conducting their own evaluations of student outcomes. To facilitate this process, we collaboratively developed templates and guidance for teachers’ measurement and reporting of student growth, provided training and technical assistance as teachers prepared student outcome data, and guided teachers in reflecting on results to improve their practice. The evaluators then aggregated fellows’ student outcome reports to assess the program’s …

The Differences Between College Readiness And The Type Of Algebra 1 Course Taken By Male And Female Students Attending A Private School In Southwestern Virginia, Christina M. Perdue

Doctoral Dissertations and Projects

Algebra 1 is a foundational course for all higher mathematics. Research suggests taking rigorous math courses earlier in a student’s education increases college readiness which leads to a greater economic impact to the community. The purpose of this quantitative causal-comparative study was to determine if there is a difference between male and female students’ college readiness as measured by the mathematics test scores of the PSAT/NMSQT of students who have taken an Algebra 1 course, designated as either Honors or Non-Honors section, who attend a private high school.

The Impact Of Edwards V. Aguillard On Science Education In Louisiana Public Schools, Abigail Mcdonough

Senior Honors Theses

The landmark Louisiana case Edwards v. Aguillard ushered in a new era of legislation in which certain ideas are discriminated against because of their religious basis. Due to the Court’s misinterpretation of evidence and employment of a faulty test for a secular purpose, the Court is responsible for disastrous and far-reaching implications. This thesis will examine how the 1987 Supreme Court case Aguillard shifted American science education away from the exploration of multiple competing theories of man’s origins in the classroom. Although America was founded on principles such as freedom of religion and thought which should be protected, the Aguillard …

Understanding Second Grader’S Computational Thinking Skills In Robotics Through Their Individual Traits, Youngkyun Baek, Dazhi Yang, Yibo Fan

Educational Technology Faculty Publications and Presentations

This study investigated the relationship between the personal traits and computational thinking skills of second graders within the context of robotics activities. The hypothesized model showed that learning preference, intrinsic motivation, and self-efficacy were the main predictors of coding achievement and computational thinking skills, while no direct relationship was found between learning preference, intrinsic, or extrinsic motivation. The final path analysis revealed that intrinsic and extrinsic motivation predict self-efficacy, self-efficacy predicts coding achievement, and coding achievement predicts computational thinking skills. Another important finding was the strong impact of self-efficacy on coding achievement as well as computational thinking skills. Results are …

Alignment Of Theoretically Grounded Constructs For The Measurement Of Science And Chemistry Identity, Kathryn Nicole Hosbein, Jack Barbera

Chemistry Faculty Publications and Presentations

Identity has been theorized to aid in student persistence within STEM disciplines. In this study, science and chemistry identity were defined as being recognized as a science or chemistry person within the classroom. To generalize the effects that identity has on student persistence, a measurable construct must be defined, operationalized, and tested in multiple settings with different populations. This project addressed the first step in the process, defining the construct and grounding it in an established theoretical framework. This qualitative project utilized a previously described physics identity framework, with sub-constructs of performance/competence, recognition, and interest, as a starting point for …

Dominant And Critical Mathematics: A Multi-Case Study Examining Mathematics Teachers’ Equitable Teaching Practices, Laura Zamudio

FIU Electronic Theses and Dissertations

In the field of mathematics education, it is common for studies to use test scores to examine racial and socio-economic achievement gaps. The results of such studies have influenced mathematics teachers to address issues of equitable access and achievement as part of closing existing gaps (Gutiérrez & Ezekiel Dixon-Román, 2011). However, closing achievement gaps does not mean that equity has been addressed if marginalized students continue to express a cultural disconnect from the field of mathematics (Lubienski & Gutiérrez, 2008).

This qualitative multi-case study seeks to attend to these issues by exploring the understandings of equity and equitable teaching practices …

Supporting Prospective Teachers’ Development Of Relevant And Authentic Mathematics Stories, Eryn M. Stehr, Lindsay M. Keazer

Education Faculty Publications

Supporting prospective elementary teachers (PTs) to develop mathematics problems with contexts that reflect their students’ lives is a challenge that remains to be explored. We began this work by conducting collaborative action research to explore PTs’ development of mathematics problems that were relevant and authentic to PTs’ own lives. We engaged in iterative cycles of action research by asking PTs to write mathematics stories, followed by our review and discussion of the themes we saw and sharing selected examples with PTs during class discussions. Findings after three cycles of data collection suggest that PTs’ mathematics contexts became more story-like and …

Modeling Potential Energy Of The Gaussian Gun, Leslie Atkins Elliott, André Bolliou, Hanna Irving, Douglas Jackson

Curriculum, Instruction, and Foundational Studies Faculty Publications and Presentations

The Gaussian gun is an arrangement of magnets and ball bearings (pictured in Fig. 1) such that—when the leftmost ball is released—the rightmost ball is ejected at high speeds. The device has been described in several articles on energy education. The sudden appearance of kinetic energy offers a productive context for considering a range of challenging ideas: the often-counterintuitive relationship between force and potential energy, the escape velocity for attractive forces, why energy is required to break bonds, and why energy is released when bonds form. Beyond these ideas, it is also useful for motivating the representation of a potential …
